Suites of Best Management Practices (BMPs) are usually selected to be economically and environmentally efficient in reducing nonpoint source (NPS) pollutants from agricultural areas in a watershed. The objective of this research was to compare the selection and placement of BMPs in a pasture-dominated watershed using multiobjective optimization and targeting methods. Two objective functions were used in the optimization process, which minimize pollutant losses and the BMP placement areas. The optimization tool was an integration of a multi-objective genetic algorithm (GA) and a watershed model (Soil and Water Assessment Tool—SWAT). For the targeting method, an optimum BMP option was implemented in critical areas in the watershed that contribute the greatest pollutant losses. A total of 171 BMP combinations, which consist of grazing management, vegetated filter strips (VFS), and poultry litter applications were considered. The results showed that the optimization is less effective when vegetated filter strips (VFS) are not considered, and it requires much longer computation times than the targeting method to search for optimum BMPs. Although the targeting method is effective in selecting and placing an optimum BMP, larger areas are needed for BMP implementation to achieve the same pollutant reductions as the optimization method.

Florida is the second leading horticulture state in the United States with a total annual industry sale of over $12 Billion. Due to its competitive nature, agricultural plant production represents an extremely intensive practice with large amounts of water and fertilizer usage. Agrochemical and water management are vital for efficient functioning of any agricultural enterprise, and the subsequent nutrient loading from such agricultural practices has been a concern for environmentalists. A thorough understanding of the agrochemical and the soil amendments used in these agricultural systems is of special interest as contamination of soils can cause surface and groundwater pollution leading to ecosystem toxicity. The presence of fragile ecosystems such as the Everglades, Biscayne Bay and Big Cypress near enterprises that use such agricultural systems makes the whole issue even more imminent. Although significant research has been conducted with soils and soil mix, there is no acceptable method for determining the hydraulic properties of mixtures that have been subjected to organic and inorganic soil amendments. Hydro-physical characterization of such mixtures can facilitate the understanding of water retention and permeation characteristics of the commonly used mix which can further allow modeling of soil water interactions. The objective of this study was to characterize some of the locally and commercially available plant growth mixtures for their hydro-physical properties and develop mathematical models to correlate these acquired basic properties to the hydraulic conductivity of the mixture. The objective was also to model the response patterns of soil amendments present in those mixtures to different water and fertilizer use scenarios using the characterized hydro-physical properties with the help of Everglades-Agro-Hydrology Model. The presence of organic amendments helps the mixtures retain more water while the inorganic amendments tend to adsorb more nutrients due to their high surface area. The results of these types of characterization can provide a scientific basis for understanding the non-point source water pollution from horticulture production systems and assist in the development of the best management practices for the operation of environmentally sustainable agricultural enterprise

Best management practices in green lodging are sustainable or “green” business strategies designed to enhance the lodging product from the perspective of owners, operators and guests. For guests, these practices should enhance their experience while for owners and operators, generate positive returns on investments. Best management practices in green lodging typically starts with a clear understanding of each lodging firm’s role in society, its impact on the environment and strategies developed to mitigate negative environmental externalities generated from the production of lodging goods and services. Negative externalities of hotel operations manifest themselves in energy and water usage, waste generation and air pollution. Hence, best management practices in green lodging are dynamic, cost effective, innovative, stakeholder driven and environmentally sound technical and behavioral solutions that attempt to ameliorate or eliminate the negative environmental externalities associated with lodging operations, while simultaneously generate positive returns on green investments. Thus, best management practices in green lodging should reduce lodging firms’ operating costs, increase guest satisfaction, reduce or eliminate the negative environmental impacts associated with hotel operations while simultaneously enhance business operations.

The Mara River in East Africa is currently experiencing poor water quality and increased fluctuations in seasonal flow. This study investigated technically effective and economically viable Best Management Practices for adoption in the Mara River Basin of Kenya that can stop further water resources degradation. A survey of 155 farmers was conducted in the upper catchment of the Kenyan side of the river basin. Farmers provided their assessment of BMPs that would best suit their farm in terms of water quality improvement, economic feasibility, and technicalsuitability. Cost data on different practices from farmers and published literature was collected. The results indicated that erosion control structures and runoff management practices were most suitable for adoption. The study estimated the total area that would be improved to restore water quality and reduce further water resources degradation. Farmers were found to incur losses from adopting new practices and would therefore require monetary support.

Agriculture is one of the major sources of greenhouse gas (GHG) emissions accounting for approximately 14 percent of total GHG emissions. However, unlike other sectors such as transport or energy, agriculture is potentially a significant carbon 'sink'. Moreover, because the majority of GHG emissions from agriculture originate in developing countries, early intervention could be highly cost-effective. This note examines the potential role of agriculture in climate change mitigation. It discusses: 1) the sector's current GHG emissions, 2) its potential to serve as a sink, 3) best management practices that can be adopted to mitigate climate change, and 4) social and institutional barriers to adopting agricultural mitigation measures, and ways to overcome them.

Projeções em modelos climáticos globais quanto às emissões de gases de efeito estufa apontam um aumento na intensidade e frequência dos eventos extremos de chuva, que, associado ao crescimento urbano e à expansão das superfícies impermeáveis, deverá gerar impactos sem precedentes sobre a infraestrutura de drenagem. Diante desse cenário, as cidades têm a oportunidade de realizar uma transição infraestrutural ao adotar técnicas de Melhores Práticas de Manejo (MPM) das águas de chuva como solução mais sustentável, resiliente e integrada à paisagem urbana. Este estudo apresenta uma comparação qualiquantitativa entre reservatórios de detenção e MPM dos escoamentos como estratégias de controle pluvial. Considerando uma microbacia urbana na Região Metropolitana de São Paulo (RMSP), onde foram instalados dois reservatórios com volume de detenção total de 19.200 m3, distribuíram-se elementos debiorretenção e passeios porosos nas vias públicas localizadas na área de contribuição da bacia. O volume de retenção das técnicas propostas como tratamento dos espaços abertos públicos corresponde a 42% da capacidade de detenção dos reservatórios. Confirma-se, então, a viabilidade das MPM como alternativas para adaptação das cidades às mudanças climáticas...

Stormwater runoff from urban land has become a challenge for growing communities in managing non-point source pollution. The stormwater runoff of Downtown Durham, North Carolina is of particular interest, due to its location relative to the Falls Lake Reservoir. The purpose of this study is to use monitoring and modeling data to determine the best management of the Duke Diet and Fitness Center property, which drains 474 acres of urban land in Downtown Durham. Monitoring data was collected at this site for 9 storm events from July to October, 2010 and then analyzed for total nitrogen and phosphorus concentrations. The Jordan/Falls Lake Stormwater Accounting Tool and the Upper Neuse Site Evaluation Tool were used to determine nutrient loads and peak flow rate for 4 management scenarios using Best Management Practices (BMPs) in the drainage catchments. Based on these results, we give our recommendation for the construction of a wet pond at the site which will significantly reduce peak flow and nutrient loads from Downtown Durham.

Nonpoint source (NPS) pollution is a pervasive problem throughout the United States. In coastal North Carolina, NPS most commonly takes the form of stormwater carrying large quantities of bacteria into neighboring estuarine waterways. Elevated levels of bacteria can have significant effects on water quality and result in area closures for commercial shellfish harvesting. This masters project investigates stormwater retrofitting potential in a small coastal neighborhood located within the White Oak River watershed. Applying Geographical Information Systems (GIS) to estimate impervious surface and model stormwater runoff, a mixed method approach is used to better evaluate areas of concern within a subwatershed of the White Oak River. In analyzing both state-level stormwater management guidelines and interviewing local residents on their perceptions of water quality, a goal of this study is to determine what considerations are needed to guide current and future stormwater projects. The results of this study indicate that the current stormwater regulatory framework operates on a temporal scale that hinders comprehensive funding, implementation, and monitoring of Best Management Practices (BMP) retrofitting projects. Modifications on the subwatershed level highlight impervious surface coverage from development may be significantly increasing sheet stormwater runoff. Qualitative findings demonstrate the educational outreach could be useful in gaining community support for future BMP projects. Further research in applying participatory mixed methods to study local stormwater may provide greater stakeholder engagement and successful implementation of low-cost BMPs in continuing efforts of water quality improvement.

The deteriorating conditions of aging infrastructure in United States cities have been challenging municipalities for years. In 2013, the American Society for Civil Engineers gave US infrastructure a D+ for the current conditions of infrastructure including roadways, waterways, levees and bridges1. When the current need to improve ailing infrastructure is combined with the 1990s shift in transportation planning, Best Management Practices call for transportation systems to consider the needs of drivers, pedestrians, bicyclists, and people with physical and metal challenges, the elderly and children equitably.3 Smart Growth America’s National Complete Streets Coalition touts more than 600 member cities as of January 2014.4 Each of the member cities is altering its existing transportation system by adopting “laws, resolutions, executive orders and policies” that ensure all stakeholders have equitable access to their local transportation system.4 Cities across the nation, including San Francisco, Philadelphia and New Orleans, have passed Executive Orders and ordinances to help ensure their constituents have equitable access to the transportation system. Working closely with organizations such as Smart Growth America and local advocacy groups...

Corporation X owns and operates Port Y in Indonesia and will begin using Port Z in Australia, a public port, in late 2008. The ports are used to export copper concentrate, while Port Y is also used to move commodities, cargo, and people. Analysis based on field observations and personnel interviews revealed strengths and weaknesses in best management practices at each location. As the Corporation aims to demonstrate best port practices, this assessment of environmental practices and protocols addresses handling of cargo, protocols for ships, environmental controls, monitoring, and general practices. Research found that Port Y could lessen environmental impacts by enclosing the copper concentrate conveyor system. Best practices at Port Y include ballast water management and monitoring practices. Port Z could improve its management practices by increasing environmental monitoring frequency; best practices include movement of copper concentrate and air quality maintenance.

This study has been created to analyze current stage of tourism development in Republic of Croatia, as well as to show prospective ways for improved tourism and economic development in the future. The focus is on both macroeconomic and microeconomic .aspects. The study shows how to use some of the best management practices - system dynamics, systems thinking, breakthrough thinking, benchmarking and delivering profitable value - in scenario planning for Croatian tourism and economic development. The transition process brings about numerous challenges to every aspect of life, but especially in economics. Government administrators, economists, tourism planners, corporate managers and university professors can find the best way to deal with these challenges in such increasingly complex environment. Traditional styles and practices in both knowledge delivery and implementation of actions are often limited when the focus is on ambiguous and interrelated problems within complex systems. A new systematic and organized approach should be established for fostering the problem solving, critical thinking and scenario planning skills. The idea is to familiarize those in charge of tourism and economy development in Croatia with a new approach, derived from best management practices. Breakthrough thinking shows that the same or very similar practices can be used in management of an enterprise...

Joshua M. Duke; This paper examines the effectiveness of a proposed nutrient offset trading market at increasing adoption rates of best management practices (BMPs) in the Chesapeake Bay Watershed. The analysis incorporates real agronomic data collected from farms on Maryland???s Eastern Shore to accomplish three study objectives: (1) derive the farms??? demand to adopt BMPs; (2) determine the heterogeneity of nutrient reductions for various farms; and (3) estimate the likely participation in the proposed program. Seventy-seven low-load fields were entered into the Maryland Nutrient Trading Tool where reductions were calculated from the planned installation of four management practices: Forest and grass buffers, decision agriculture, and land use conversion. Estimated costs of BMP adoption and credit values were applied to generate net benefits of adopting a BMP in the offset trading market, from which participation was then estimated. The results showed the trading tool creates heterogeneous reductions in nutrient loadings. Second, the incentives derived from the program are only likely to incentivize riparian buffer adoption, a practice that is likely already fully incentivized. This may lead to low participation rates within the program. Finally...

Chirnside, Anastasis; The purpose of this project was to develop Water Quality Indices (WQI) that could be utilized to describe the water quality in the Cool Run tributary and to evaluate the impact of BMP implementation within the University of Delaware Agricultural Experimental Station Farm (UDAESFF) on water quality. A variety of water quality parameters have been measured at eight sites within the UDAESF over the past three years. Based on this data there has been a positive impact on the water quality as Cool Run exits the UDAESF and continues through residential areas. Many sections of the stream within the UDAESF are still impaired from previous farm management practices. New management practices have been implemented during the study period these include a manure collection system and a constructed wetland. Older management practices have been in place since before 2001, these practices include riparian buffer zones, prevention of livestock from entering the stream and the addition of a weir. A working model was developed to allow the WQI to be used for the evaluation of up to eight different parameters sets or to be used to create a spatial distribution of the WQI values as the stream flows through the UDAESF. The model was used for the evaluation and rating of the individual sites and the Best Management Practices (BMPs) that are in place. Evaluations were completed using the effects on streams associated with the individual BMPs and parameters that related general stream health. Future researchers will be able to use and update the Kiliszek Water Quality Index (KWQI) with the current Delaware water quality standards and criteria to monitor the quality of water within the Cool Run Stream.; University of Delaware...

Background/Questions/Methods Animal agriculture in the Spring Creek watershed of central Pennsylvania contributes sediment to the stream and ultimately to the Chesapeake Bay. Best Management Practices (BMPs) such as stream bank buffers are intended to intercept sediment moving from heavy-use areas toward the stream. The placement of BMPs on a farm is generally based on untested assumptions about flow paths. Most often, a straight-line distance from the heavy-use area to the stream is assumed to be correct. Our objective was to compare the straight-line path to hydrologic flow paths calculated from fine-, medium- and coarse-grained Digital Elevation Models (DEMs; 1m, 10m, 30m) for 471 mapped heavy-use points within 100m of the stream. The 30m DEMs are the most widely available and require the least processing time. We anticipated that the flow path distance would be longer than the straight-line distance in all cases, that the finest resolution would lead to the most accurate measurement, but that the difference might not be great enough to justify the increased costs. Understanding the changes in path length and direction calculated using more complex methods and higher-resolution source data will enable us to make recommendations on methods to be used in developing conservation management plans. Results/Conclusions The medium-(10m DEM) and fine-resolution data (1m DEM) had the smallest differences between the hydrologic flow path and straight-line path: median differences in path length of 20 m for both the 1m and 10m DEMs...

The main aim of this study was to assess the impact of the Best Management Practices (BMP) project on social and economic wellbeing at the Zanyokwe Irrigation Scheme (ZIS) in central Eastern Cape Province. The BMP project is a knowledge-based initiative aimed at introducing management practices in order to improve production and livelihoods in the study area. The study employed a survey to collect socio-economic data amongst farming households. The 2005 (pre-BMP project) baseline study based on the same respondents allowed for the tracking of changes after the implementation of the project. A socio-economic impact assessment (SEIA) framework was used to assess the impacts. The results showed the BMP project to have impacted on social and economic wellbeing of households. Skills introduced were in the areas of water management, agronomic practices, marketing and institutional arrangements. In 2007 more than half of farmers worked on their farms daily, an improvement on 2005, when none of the farmers reported working over weekends. The average time spent on the farms per day also increased from 4 (in 2005) to 7 h (in 2007). Agriculture's contribution to household income improved from 71% in 2005 to 81% in 2007 and reduced household poverty and food insecurity levels. The number of households earning incomes below the poverty line dropped from 61°% in 2005 to 38% in 2007. A marked increase was noted in winter land use...
